Things I Wish I Knew Before Getting A Second Dog

Oct 17, 2025byMichael Tremblay

Adding another furry friend to your family sounds exciting, right? You already know how to care for one dog, so bringing home a second should be simple. However, many owners discover that doubling the canine count comes with unexpected challenges and surprises that catch them off guard.

This article provides general advice based on common experiences. Every dog is unique, and individual circumstances vary. Consult with a veterinarian or professional dog trainer for personalized guidance.

Many people assume their current pup will instantly love having a playmate. Reality often looks different. Some dogs enjoy being the only child and feel stressed when sharing their space, toys, and your attention.

Jealousy can surface in surprising ways, from guarding favourite spots to acting out for attention. Proper introductions matter tremendously, so take time letting them meet on neutral ground first.

2. Double The Dogs Doesn’t Mean Double The Work

Here’s a pleasant surprise: caring for two dogs isn’t twice as hard as caring for one. They often entertain each other, reducing boredom and destructive behaviour when you’re away.

Feeding time becomes slightly longer, and vet bills do increase. But the emotional workload decreases because they have companionship. Walking both together gets easier with practice, especially once they learn to move as a team.

3. Training Becomes More Complex

Training one dog requires focus and consistency. Adding another creates distractions that complicate the process significantly. Your new dog needs individual training sessions, away from your first pet, to learn basic commands properly.

Dogs can pick up bad habits from each other faster than good ones. If your first dog barks at visitors, the second might copy this behavior immediately.

4. Space Requirements Increase Significantly

One dog fits comfortably in most apartments or smaller homes. Two dogs need considerably more room to move, play, and claim their own territories without constant conflict.

Each dog benefits from having personal space where they can retreat and relax alone. Food bowls, water dishes, beds, and toys all need thoughtful placement to prevent resource guarding between your pets.

5. Expenses Add Up Faster Than Expected

Beyond doubling food costs, you’ll face increased veterinary expenses, grooming bills, and boarding fees whenever you travel. Emergency vet visits become twice as likely with two dogs in the household.

Pet insurance premiums, preventative medications, and annual checkups multiply quickly. Budget carefully before committing, ensuring you can comfortably afford quality care for both animals throughout their entire lives together.

6. They May Bond More With Each Other

Sometimes dogs become so attached to each other that their bond with you weakens slightly. They seek comfort from their canine companion first, especially during stressful situations or when feeling anxious.

This isn’t necessarily bad, but it changes the dynamic you enjoyed with your first dog. Maintaining individual time with each pet helps preserve your special connection while letting them enjoy their friendship too.

7. Separation Anxiety Can Develop Between Them

When dogs spend all their time together, they can become overly dependent on each other’s presence. Taking one to the vet or groomer without the other might trigger anxiety in both animals.

This codependency creates challenges when circumstances require separating them temporarily. Practicing regular solo outings with each dog helps prevent this issue from developing into a serious behavioural problem requiring professional intervention.
